Answer:

Explanation:

The volume of the milk in the measuring cup does not change when it is transferred to the mixing bowl.

Volume is the amount of space a body or substance occupies.

It is determined by the amount of matter that is present within a given measurement.

Since the amount of milk was accurately measured out, the volume is maintained when it is transferred to the mixing bowl. The reason why a measuring cup is used is to keep the consistency of the measurement.

The maximum depth of Lake Tahoe is 99.6 rod. How deep is Lake Tahoe in fathoms if one fathom-0.364 rod? ball part 250-300 fathom

Romashka [77]

Answer:

273.9 fathom

Explanation:

Fathom (ftm) and rod are the units of length used in the imperial and the U.S. customary systems.

Fathom is an unit used for the measurement of depth of water. It is equal to 1.8288 m.

Rod, also known as perch or pole, is equal to 5.0292 m.

∵ 1 fathom = 0.364 rod

and 1 rod = 2.75 fathom

∴ 99.6 rod = 99.6 × 2.75 fathom = 273.9 fathom

<u>Therefore, maximum depth of Lake Tahoe = 99.6 rod = 273.9 fathom</u>

A student uses 3.00g of a fertilizer with an npk ratio of 15-15-10, how much mgnh4po4*6h2o (mm =245.1 g/mol) should the student

postnew [5]

The correct answer is 8.89 g.

The production of MgNH₄PO₄.6H₂O is given by the equation:

NH₃ + H₃PO₄ ⇒ (NH₄)H₂PO₄

(NH₄)H₂PO₄ + MgSO₄ + 6H₂O ⇒ MgNH₄PO₄.6H₂O + H₂SO₄

This is the real fertilizer of NPK of weight 3 g.

It is given that the NPK is present in the ratio of 15-15-10.

Therefore, the moles of phosphorus found in the actual fertilizer is as follows:

% of P present as P₂O₅ in the fertilizer is (15/40) × 100 = 37.5 %

% of P = mass of P / actual mass of fertilizer

0.375 × 3 = mass of P

Mass of P = 1.125 g / 31

Moles of P = 0.03629 mol

On the basis of reaction stoichiometry,

1 mol of P in the actual fertilizer = 1 mol of P in the product

0.03629 of P

Moles of MgNH₄PO₄.6H₂O = 0.03629 mol

Mass of MgNH₄PO₄.6H₂O formed = 0.03629 mol × 245.1 g/mol

= 8.89 g

Thus, the mass of the product MgNH₄PO₄.6H₂O formed is 8.89 g.

Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm.

Ket [755]

Answer:

4.85 x 10⁻¹⁹J

Explanation:

Given parameters:

Wavelength = 410.1nm

Unknown:

The energy of the violet light = ?

Solution:

The energy of a wave can be derived using the expression below;

E = $\frac{hc}{wavelength}$

h is the planck's constant

c is the speed of light

Insert the parameters and solve;

E = $\frac{6.62 x 10^{-34} x 3 x 10^{8} }{410.1 x 10^{-9} }$ = 4.85 x 10⁻¹⁹J

Calculate the volume of dry CO2 produced at body temperature (37 ∘

ra1l [238]

Using the equation PV = nRT
Therefore; V = nRT / P
Need moles of glucose converted to moles of the product gas (CO2).

Molecular weight calculation:
C 6 X 12.01 = 72.06
H 12 X 1.01= 12.12
O 6 X 16.00 = 96.00
sum = 180.18
25.5 g of C6H12O6 ( 1 mol C6H12O6 / 180.18 g) ( 6 mol CO2 / 1 mol C6H12O6) = 0.84915 mol CO2 gas.
Convert temp: 37 °C + 273.15 = 310.15 K
V= ((0.84915 mol)× (0.0821 L atm / mol K) (310.15 K))/0.980 atm
V = 22.0635 L
= 22.06 L CO2
